If downtime is not an option, there is a growing industry around recovery as a service (Raas)… There are more than 50 providers in this space now, Morency says, ranging from big-name IaaS providers such as Amazon, Microsoft, Terremark and Sunguard, to other players such as Bluelock, Hosting.com and HP, along with others. These providers work with customers to create customized backup solutions, mostly on the IaaS side, but sometimes on the SaaS side as well, Morency says.
